GLASS-BLOWIN G MACHINE.

Application filed August 27, 1923. Serial No. 659,451.

My invention relates to that type of ma chine for blowing bottles or other hollow glass articles, wherein there are two separate tables mounted for continuous rotation, these two tables designed to carry the blank or parison molds and the finishing molds respectively.

According to my invention, the blank-mold table and the finishing mold table are arranged side by side and spaced apart with their adjacent portions moving in the same direction, in order that a transfer of the parison from the blank mold to the finishing mold may be effected during the time that'such molds are adjacent each'other and moving in the same general direction.

An object of this invention is the provision of a machine of: the above character, in which a blank or parison is carried on the'blank mold table to a predetermined point, then re leased from the blank mold and inverted by a transfer head on said table and brought by said head toa suspended position above and in alignment with the finishing mold bottom plate on the second table, where it is immediately enclosed by the finishing mold.

A further object is the provision of a continuously operating two-table machine, wherein the article being produced is under positive control from the momentthe charge is received'into the blank mold on the first table until it has been given its final shape in the finishing mold on the second table.

A further object is to avoid the necessity of inverting the blank mold on this type of machine. e

Other objects of the invention ,will appear hereinafter.

Referring particularly to Figures 1 and 2 of the drawings, 30 designates a base or platform adjacent one end of which is erected a column 31 designed to support the blank mold carriage 32. A similar support or colof the fi ishing 1mm 33 is erected on the base adjacent the other end thereof and supports the blow mold carriage 34. The mold tables 32 and 34 are mounted for rotation on roller bearings 35 and 36 (Fig. 3).on drum castings 37 and 38 respectively and are driven by a motor (not shown) having driving connections with annular gears 41 and 42 on the blank and finishing mold cagriages respectively. These mold carriages re each adapted to carry a plurality of mold units hereinafter more fully described and which may be of any number desired. In the present instance, five of these units have'been shown mounted on each table and as all the'units on a table are alike, a description of one will be deemed suflicient for all.

Each blank mold unit comprises a sectional body or blank mold 43 and a sectional neck mold 44. The blank mold is made in horizontally separable sections mounted on arms 45 (see F ig, 8), said arms pivoted to swing about a bearing sleeve 46. Links 47 connect the mold arms with a yoke 50 on a slide 51 (Fig. 4) which reciprocates radially in guides 52 on the mold carriage 32, said guides extending radially of the machine. The yoke 50 is connected through a link 53 to a rock arm 54 on a rock shaft 55, to which is also connected a rock arm 56 having a cam roll 57 running in a stationary cam 58. This cam is so shaped as to effect the opening and closing of the blank molds at predetermined periods, as hereinafter noted.

As the mold carriage rotates, each mold unit is brought beneath a charging feeder 60 (Fig. 4) from which charges of glass 61 are supplied. At this time, the blank mold 43 is closed and in inverted position with the.

funnel guide 62 directly above and in alignment therewith, and the neck mold 44 is beneath and locked in register with the blank mold to form the neckend of the bottle.

Each neck mold is mounted on an adjustable head 63, said head forming a part of an inverting arm 64. Projections .of this arm are formed as slideways, in which the head 63 may be vertically adjusted by means of an adjusting screw 66. This adjustment is provided to allow for difl'erent height molds. In Fig. 10 the head 63 and parts carried thereby are show in broken lines in a position of adjustment in which the center of gravity of the parison is in or a short distance above the horizontal plane of the axis of the inverting arm 64. Also the neck mold 44 or other blank holder is offset vertically and horizontally relative to the horizontal axis about which the blank swings. The arm 64 has a shaft projection 67 (Figs. 9 and 10) w mounted in a bearing block 68, said block being mounted for oscillation in a bearing 69 formed in an extension 7 O of the carriage 32. A shaft 71 extends from the bearing block through bearings 69 and has attached thereto an arm 72 carrying a cam roll 73, said roll running in a stationary cam 74. This cam controls the horizontal oscillation of the arm 64, thereby aligning the neck mold be seen that the cam 74 is so shaped that it will hold the neck mold 44 in vertical alignment with the finishing mold during a pre determined period of'its travel, in order that the blank may be blown to the shape of the finishing mold before the release of the neck mold is effected. After the neck mold carrying the bare blank has been completely inverted, a section 74 (Fig. 9) of the cam 74 is so shaped as to bring the neck mold 44 into alignment with the arc in which the tinishing mold travels at the point where radius line A crosses said are. Section 74 is shaped to guide the neck mold along the are from radius line A to radius line B and thereafter section 7 4 swings it outward from said are to point C. Its position is then controlled for a predetermined period by section 74 of the cam. Section 7 4 is shaped to swing the neck mold back into normal position.

Immediately after a charge of glass is received in the blank mold 43, the combination blow head and closing plate 75 (see Fig. 15) is moved into position over the open upper end of the mold. This head, attached to the piston rod 76 of an air motor 77. is then lowered to close the mold by admitting air above the piston 78 of said motor through a pipe 81. Air under pressure is then admitted through the head 75 to compact the glass and cause it to take the shape of the neck mold. This air is supplied through a pipe 84 and a check valve 85 in the plate, said valve normally held closed by a spring 86. The mechanism for supplying compressed air to the blowing head plate 7 5 and air motor 77, and for blowing the parison to hollow form, together with the valve mechanism for controlling the air, will now be described.

Referring to Figures 3, 4, '5, 6 and 14 to 17 inclusive, air under pressure is supplied from any suitable source through pipe 87, 87 a and 87 to a drum 37 forming part of the lower bearing of the blank mold carriage 32. The upper end of this drum is open. allowing air to pass to the passageways 89 formed in the mold carriage. A pipe 91 (Figs. 4, 6 and 17) leads from the drum 37 to a valve chest 92- mounted on an oscillating arm 93, this arm also carrying the air motor 77. Air under pressure is admitted to themotor 7 7 through pipes leading from the valve chest 92 in which are mounted valves 95.

Rigidly attached to the column 311s a hen 1'- ing bracket 220 (Fig. 6) having mounted thereon a shaft 221. Attached to the lower end of this shaft is a pinion 222 running in mesh with a ring gear 223, said ring gear attached to the mold carriage 32 and rotating therewith. Fastened to the upper end of shaft 221 is a pinion 224 running in mesh with a pinion 225, said pinion attached to one end of shaft 226. On the opposite end of this shaftis m unted. a crank arm 227 carrying a roll 228, said roll running in a groove 229 formed in the blow head arm 93. Due to the rotation of ring gear 223 it will be seen that through the above mechanism;crank arm 227 will be' rotated, thereby oscillating the arm 93 to and fro through a certain arc. The groove 229 is so shaped that the crank arm 227 will advance the arm 93 at the same angular speed as the mold carriage during the time the plate is in its lowered position for closing the mold. N ow, as the valve chest 92 and its actuating levers are carried by the arm 93, it will be noted that during the movement of the arm, the stationary cams 101, 102 and 103 will actuate the valves as follows: It will be supposed that blow head 75 is above and in register with a blank mold and'just started on its clockwise movement. T hese valves are actuated by levers 96, 97 and 98 controlled respectively by stationary cams 101, 102 and 103 mounted on the column 31. The cam 103 will operate at 103 (Figs. 18, 19) through the lever 98 to open its valve and supply air through pipe 81 to the upper end of cylinder 77, thereby lowering the plate 75, holding said plate lowered until reaching cam section 103 where the valve is closed. The cam 102 operates at 102 through the lever 97, whereby its valve is opened and air is admitted through pipe 84, passages 104 and 105 (Fig. 15) in the piston and piston rod, then past the check valve 'to the upper end of the mold 43 to compactthe glass and insure a good neck finish. A section 102 is arranged to shut off the blowing air after a predetermined time interval. The cam 101 is arranged to actuate lever 96 to admit air through pipe 88 to raise the plate 75 immediately after section 103 closes off the air to the upper endof the cylinder. Springs 106 hold the valve lovers in contact with their cams.

After the neck has been finished, the neck pin or plunger 107, which has been held in position in the neck mold 44 by a stationary cam 108 (Figs. 1 and 4), is released and withdrawn. This neck pin is mounted in a holder 110, said holder mounted to reciprocate in the head 63 and normally held retracted by the spring 111. After the plunger is retracted and the air through plate 75 isdisc-ontinued, a blow arm 112 (Figs. 6 and 16) pivoted on the carriage 32 is swung about its fulcrum 113 by a cam section 114 of cam 114 contacting with a roller 115 on said arm. \Vhen the blow arm 112 swings from the Figure 4 position to that shown in Figures 6 and 16,. air is admitted from chamber 89 (Figs 4, 5 and 6) through pipe 117, passages 118 and 119, (Fig. 7) pipe 121 (see Fig. 16) to, the blow arm, thence through passageways 122 and 123 in the neck pin holder and neck pin respectively to supply an initial blow tothe blank. The raising an lowering of the blow arm controls the admittance of air to the blank mold for the initial blow. \Vhen arm 112 is in the Figure 6 position, opening 121 of the arm is in communication with opening 119 in shaft 113, thereby allowing air to pass to the neck molda \Vhen the arm is lowered, the air is automati oally shut off. After .the blank has been blown to hollow form, the blankmold opens, leaving the hollow blank projecting upward from and supported by the neck mold 44 on the head 63. This brings the operation up 'to the point shown inFigures 10 and 14.

. Attached to the shaft 67 of the inverting arm 64 (see Fig. 10) is a bevel gear 125 runnin in mesh with a gear 126 on a shaft 127 of thebearing block 68. The gear 126 has a projecting sleeve 128 on which is mounted a pinion 129. Runnin in mesh with this pinion is a rack 131 (see Figs. 8 and 4) mounted for horizontal reciprocation in a standard 132. Attached to one end of the rack is a cam roll 133 controlled by a stationary cam 134, said cam shaped to operate to invert and reinvert the neck mold carrying head 63 at predetermined intervals. Projecting lugs 135 and 136 (Fig. 14) of the arm 64 limit its movement in either direction by contacting with a pin ,v 137 projecting from the bearing block 68.

When the operations have progressed to the point indicated in Figure 9, a section 134 (Fig. 8) of the cam 134 operates to move the rack 131 radially outward, thereby operating through the connections above described to invert the head 63 from the full line position, (Fig. 14), to the dotted line position, bringing the parison to a position pendent from the neck mold and in register with a mold bot. tom plate 140 on the finishing mold carriage 34 at the point where radius line A (Flg. 9) crosses the arc of thefinishing mold. It will be observed that when the inverting head 63 is adjusted to the dotted line position shown in Fig. 10, the longitudinal axis of the parison which is vertical (see Fig. 14) is substantially perpendicular to a radial line drawn from the axis of rotation of the inverting head to the center of gravity of the parison. It will thus be seen that the longitudinal axis of the blank is substantially tangent to the are which defines the movement of the center of gravity of the blank relative to the axis of inverting movement of the blank. The cam'134 is shaped at 134 to allow freedom of movement of the camroll 133 in order that there may be no turning or inverting movement of the arm 64 during its horizontal .movement, while traveling in alignment with the finishing mold from radius line A to line,B (Fig. 9). When the inverting arm 64 reaches the position shown in Figure 8, the cam roll 133 is just entering the, section 134 of the cam 134. this section being so shaped that the head 63 is quickly swung up to the po sition shown in Figure 5. so that during the continued travel of the tables there may be no interference between the neck molds 44 and the neck of the bottle which is pro ectln'g from the finishing mold. The section 134 blends into section 134 which is shaped to complete the inverting movement of the arm 64 during the further travel of the mold carrlage 32.

Each complete finishing mold iinit comprises a sectional finishing mold 141 and a bottom forming plate 140. The mold comprises separable mold sections mounted in arms 142 pivoted to swing about a bearing sleeve 143. Links 144 connect the mold arms with a yoke 145 on a slide 146 which reciprocates in guides 147 on the carriage 34. The yoke 145 is connected through a link 148 to a rock arm 150 on a rock shaft 151, to which is also connected a rock arm 152 having a cam roll 153 running in a stationary cam 154. This cam is so shaped as to effect the opening and closing of the mold at intervals, as hereinafter noted. As the mold carriage 34*rotates, each mold 141 is brought to a position at the radial line A (Fig. 9) where the parison is received into the finishing mold. The further rotation of the finishing mold table causes the molds to close about the parison so that it may be entirely enclosed upon reaching the radius line B. Section 154 (Fig. 2) of the cam 154 is shaped to have the molds 141 just about closed upon reaching radius line A.

Mounted upon and extending upward from the mold carriage 34 are vertical uprights 155 therewith a predetermined (Figs. 1, 2 and 21). A ring gear 156 having lug extensions 157 is arranged upon these uprights for travel with the carriage. Mounted upon the column 33 is a bearing casting 160 (Fig. 21) having formed at its outer end a bearing 161 and in which is freely mounted a shaft 162. Attached to the lower end of this shaft is a pinion 163, said pinion running in mesh with the ring gear 156. Attached to the upper end of the shaft 162 is a cam 164 in which runs a cam roll 165, said roll mounted on a blow head carrying arm 166. This blow head arm is mounted for oscillation on the column 33 and carries a pair of blow head cylinders 167 and 168 and a neck mold opening cylinder 169 (Fig. 20).

Referring to Figures 20,21 and 24, it will readily be seen that the rotation of the carriage 34 will transmit motion from the gear ring 156 to pinion 163, which in turn rotates the cam 164, thereby oscillating the blow head arm 166 from the full line position Fig. 24, to the dotted line position. The cam 164 is shaped, as clearly illustrated in Figure 24, so that as it rotates. the arm 166 will be reciprocatcd to and fro through a short are in timed relation to the molds. The oscillation of this arm'allows the blow head cylinders 167 and 168 to register with two adjacent finishing molds at a certain oint and travel distance in order that the parisons in said molds may be blown to their finished form. The blow head cylinder 167 meets amold at the line D (Fig.

9) and travels therewith to the line B, during which time air under pressure is admitted through the blow head to shape the glass in the mold.

Referring to Figures3 and 20 to 24 inclusive, air under pressure is supplied through a pipe 87 to the drum 38, said drum being open at its upper end to allow air to pass into the passageways 171 formed in the finishing mold carriage 34. Air from this drum passes through pipe 172 (Figs. 3 and 20) to pipes 190, 192 and 203. A branch 176 leads to a valve casing 177 (Figs. 24 and 22) mounted on the stationary bearing casting 160. Mounted on the shaft 162 are two cams 178 and 179 for actuating valves 181 and 182 respectively. lVhen the blow head cylinder 167 brought into alignment with the mold at line D, a section 179 (Fig. 23) of the cam 1T9 actuatcs valve 182, admitting air from pipe 176 to passage 183 of the valve casing and to passage 184 of the valve 182, thence through pipe 185 and to the upper end of the cylinder 167 to lower the piston 186 thereof. A blow head 187 mounted on the piston rod 188 is thereby brought into engagement with the plunger holder 110 (Fig. 3). Pipe 190 leading to the blow head has a constant air pressure so that when the blow head engages the neck pin holder, the piston rod continues to move downward until opening 191 in said rod is brought into alignment with the pipe 190 allowing air to pass from the blow head through passages 122 and 123 (Fig. 16) in the holder and neck pin to blow the bottle. This blowing continues until the blowing head reaches line B (Fig. 9), at which time section 179 (Fig. 23) of the-cam allows the valve 182 to close. Due to the fact that a constant air pressure is maintained in pipe 192 leading to the bottom of the cylinder 167, it will be noted that when the valve 182 closes, the piston 186 will immediately move up, withdrawing the blow head.

Slightly before the blow head is raised, the section 178 of cam 178 (Fig. 23) actuates valve 181, admitting air through pipe 193 to the upper end of the cylinder 169, thereby lowering its piston 194. Attachedto the piston rod 195 is a cam plate 196 which when lowered contacts with a stem 197 (Figs. 6, 8 and 16) mounted in the neck mold head 63. This stem is normally held projected by a spring 198, but when the cam plate is lowered the stem is pushed down and its conifcal end 200 contacts with pads 201 (Figs. 12

clear the neck of the bottle which ing from the mold (Fig. 5). The cam plate 196 is so shaped that it holds the neck molds open until they have entirely cleared. When the neckmolds have reached point C (Fig. 9) the cam 178 allows the valve 181 to return to normal position (Fig. 22), thereby shutting ofi air to the'upper end of cylinder 169. Pipe 203 is a branch of pipe 172 and, therefore, carries a constant air pressure so that the moment valve 181 tloses, the piston 194 will move upward, withdrawing plate 19.6 and allowing'the neck molds to close. At about the same time,'the section 134 of ca m 134 moves cam roll 133 inward and through the mechanism heretofore explained swings] head 63 abruptly upward about its fulcrum 67 to the position shown in Figure 5. From this point on the cam section 134 acts, due to the carriage movement, to slowly revert the head 63 back to normal position (as shown in Figs. 4 and 6) and cam section 74 of cam 74 .acts to bring'the neck molds 44 into alignment with the blank molds 43 and hold them in such position during the formation of another blank or parison.

When thelb'low head, 167 leaves the .finish-' ing mold at point B, the blank has been blown to the shape of the finishing mold, but due to the fact that the glass is still quite hot it is very possible that this shape will not be retained. Therefore, another blow head 187 (Fig. 21) has been provided, operated by a piston motor including the cylinder 168,. (see also Fig. 24), to supply a further blow or setting of the glass. This blow head is of the same construction as blow head 167 I and operates in synchronism therewith. A

branch pipe 204; leads from pipe 185 for lowcring the blow head, while pipe 205 connected to a constant supply pipe 172 operates to move the blow back to its normal position. Pipe 210 supplies blowing air to the second blow head. Air for cooling the blank molds is conducted from the drum 37 through channels 89 f rmed in the carriage 32 to the interior of the bearing sleeves-46 which, as shown in Figure 6, have ports opening into the hollow arms 45 which carry the mold sections. The air channels in the arms 45 terminate in openings 206 (Fig. 6-). The coolto that. of the blank molds.

The air.,passes from channels 171 (Fig. '3)

.in the carriage 34 to bearingsleeves 143, thence through arms" ed a bottom forming plate 140. The mold bottom is carried by a bracket 211 pivotedat 212 to permit the mold bottom to tilt and discharge the bottle after the finishing mold" is projectblow mold carriers,
